A couple questions first are you sure its the motherboard that has crapped out and not something else?How long have you had the system? is it overclocked?...when did it crap out meaning during heavy loads or normal use. Was the Error a Post Speech error or Post display error. Before running out to buy a new board i'd suggest a few home tests.Reset your CMOS chip by taking out the battery.IF problem continues, reflash your bios , that doesnt work. strip your system down, just keep you harddrive, a single chip if you have more than one and your power supply. What your error means is there is a problem with a devices which is breaking interrupts and data transferring over the I/O bus which make the memory controller in accesable by that peripheral. So it could simply be a bad peripheral why you are getting that error, or it might even be the MB. But just make sure, i've seen it happen time and time agian.
